48 Pitch 22T Pinion: Fit and Function

The Yokomo YOKPG4822 is a 48 pitch, 22-tooth pinion intended as a direct aftermarket option for electric RC applications using 48 pitch gearing. It provides the basic mechanical link between motor and drivetrain when pitch and tooth count align with the spur gear.

Select this pinion when a 22-tooth unit is required to obtain the desired final drive ratio or to replace a worn part. Always verify the spur gear pitch and motor shaft type before securing the pinion to ensure correct engagement.

Installation and tuning notes:

• Confirm the set-screw location on the motor shaft and that the pinion slides on without excessive play.
• Adjust gear mesh with a thin paper strip or feeler to achieve an ideal balance between backlash and binding.
• Once run-in is complete, re-torque the set-screw and check that mesh remains stable during loaded operation.
• Remember that changing tooth count alters acceleration and top speed, so adapt gearing and cooling as needed.
